Best way to cut old plaster with wood lathe!

This is the best way I've found to cut holes into old plaster with wood laths. I use a cut out tool with a grout/tile bit for the plaster. I than switch to a wood/drywall bit to cut the wood laths. It makes for a clean hole without damage to the ceiling or wall.

Video of the year; I loved the shot from the top. Well done

[@hockeyblitz3036]

Very well done!! Electricians love to overcomplicate things we do occasionally, but you kept it short sweet, and simple! Thanks for including/acknowledging the other tools/methods of cutting plaster ceilings

[@mattdobson123]

100%! I agree with that.. I have cut enough of these in to figure out the easiest way (for myself) glad you liked it, and thanks for watching!

[@major5maximus]

Probably best video on how to cut plaster. Thanks

[@mattdobson123]

Thank you! I really appreciate that! I hate cutting it, so the smoother and quicker it can be - the better!

[@virtuallyrealistic]

Nice video from the attic side of the wall. It shows the key plaster is preserved.

[@mattdobson123]

thanks! it took twice as long to film, but happy with the outcome!!

[@LisaGarrisonEggleston]

This is awesome. Our house was built in the 30's and we keep running into weird problems. This is very helpful. And now you smell like a baby. Adorable.

[@mattdobson123]

That is awesome, lol - smelling fresh like a baby!!

[@guscarmelo9216]

you probably dont give a shit but if you're stoned like me during the covid times then you can stream all the new movies and series on instaflixxer. Been streaming with my girlfriend for the last few months :)

[@kylostefan4661]

@Gus Carmelo Yup, I have been watching on instaflixxer for since november myself :)

[@daxenzo58]

@Gus Carmelo yup, I have been watching on InstaFlixxer for months myself =)

LOVE your baby powder tip - GENIUS! Also you vacuum taped to ladder tip was great! Thank you for sharing your experiences!

[@mattdobson123]

You are so welcome and thanks for watching!

[@peep39]

Good work. I have to cut out a door opening in my lath and plaster and I've been kicking over methods in my mind as I get closer to it

[@USMCGunner1310]

You nailed my friend..thanks for taking the time to post.

[@mattdobson123]

absolutely! glad you liked it and thanks for watching

[@clarkg9805]

This was very well done, and very informative, nice clean work thank you for sharing. I'd be interested in knowing how you tied in that piece of romex into the old knob and tube electrical system. LOL😄

2:00 *The baby/foot powder trick is LEGIT, I learned that 20 years ago when I insulated my parents attic. Also, wear/have a long sleeve work out shirt (no cotton) I keep a travel bottle in my EDC.*

[@mattdobson123]

Heck yeah!! I don't use it often, but when I need it - its awesome!

[@shifty2755]

Thank you for this brilliant video 👏

[@edward_grabczewski]

Great video and a very neat job. Thanks!

[@barclaymatheson8240]

Great tip with the baby powder.

[@hutchman0823]

Try using a carbide blade to get through plaster then switch to wood blade hole saw. Another tip is take a basketball and cut in half. Drill hole in center and use it as a dust shield.

[@mikewinburn]

Excellent presentation! Very helpful.

[@mattdobson123]

Glad it was helpful! thanks for watching and providing feedback

[@mikewinburn]

@@mattdobson123 - for sure!

[@reagan232]

I’ll be trying this soon. I live in the south, no plaster but have 3/4 inch plywood above the Sheetrock. Have about 50, 4 inch lights to put in and I know a hole saw will burn up to quickly from experience.

[@mattdobson123]

WOW!! 50 holes is a lot!! This will definitely take some time with that many holes, but any method will..

[@executorvs]

For holes, use a diamond/masonry holesaw to cut through to the wood and finish with a regular holesaw of the same size.

[@kevinhogan1584]

That’s went shockingly well

[@geordiehomza1387]

Not as helpful for cutting circular holes but the best tool I’ve found for cutting large sections out is an angle grinder with a diamond blade. We do a lot of HVAC cut-ins in old homes with no central heating and air. I can cut large 20x30” holes in about 3 minutes without burning through $30 worth of multi tool blades and no blow outs from a recip saw. Strongly recommend it for larger cuts that are square or rectangular.

[@dameonmontreal912]

Mannn thanks for the baby powder tip 💪🏾🤦🏾‍♂️

[@mattdobson123]

Any time, it works like a charm!! thanks for watching

[@alexesteban]

Would a hole saw drill work just as well?

[@mattdobson123]

A hole saw would work - but it ruins the teeth really quick.. so if you spent $15 on a holesaw vs $2 for a dremel bit, you might get upset!

[@13000voltsdc]

A 4-1/8" hole saw run backwards will take care of the plaster (or a Diamond tip Hole-saw) then run it forwards for the lathe, go get yourself a Rack A Tiers Dust bowl and your be making clean cut and dust free holes where ever you need one!!

[@allisonolassa2619]

Everything says not to use diamond on wood- but you have had success? Thx

[@josepheller8395]

I would like to ask have you had any trouble with the bots oscillating on the initial plunge? I just bought a rotozip tool from harbor freight. The first 1/8 tile bit snapped off right from the start. I bought a 5/32 tile bit and it did better but it still wants to isolate some. I tried to plunge slowly and straight in. Any tips will help. The wall is a gypsum lathe with 2 coat plaster.

[@mattdobson123]

I'm wondering if its the bits.. are they cheap one?? Some plaster can be extremely hard, so I'll sometimes use a drill bit/drill to start the hole and then switch to the rotozip.

[@josepheller8395]

@@mattdobson123 I bought roto zip carbide bits especially for tile board and plaster. I went back and got a 5/32 bit and it worked better.

[@isaidicanshout]

Can I use a bit like that in a regular drill?

[@mattdobson123]

maybe?? I don't think the RPM is high enough though??

[@divinicus]

Theres a special drill bit designed for that . Hss titanium drill and saw bits. Not sure how well they're for plaster but that's the bit for a drill

[@alexlewarex4815]

1:56 - Try coveralls, it helps

[@mattdobson123]

good point!

[@caiopereira4372]

Hi Matt, I don't know hot to private message you, would you be able to do a video on how to get in to controls and what courses to take in order to learn. Also quick question: as a foreman for a control company. does the foreman buy all the control devices (inputs/outputs) or does the plc guys provide the material for us to install ?

[@caiopereira4372]

p.s. thank you for all your help

[@mattdobson123]

sorry, missed this reply.. The job really depends on the contract and specifications.. The person buying the control devices should be spelled out beforehand.
