Test Myford Super7 - 1

[@simonconvey9645]

Dear Jan. Please could you show us your preferred method of aligning a gearbox to the leadscrew. My leadscrew is to tight in the support bushings. Slackening the gearbox mounting screws can help, but this doesn't seem like the right thing to do.

[@jansverrehaugjord9934]

Tja.. ? I assume you can measure (with an indicator) where the misalignment is, working from the reference the bed represents. That being so, I would try to do this with only the leadscrew and support bearings as well as the gearbox mounted .. to minimize the number of "uncertainties" involved. Actually, the support block and bored hole (for the leadscrew) should also be proven, as well as the leadscrew for straightness. Maybe it is a "simple" case of this not being true? Inwhich case it will bind up in some positions when you turn it around. Bending back to correct that is possible (various methods), but must be done with care and patience.

Very nice smooth running machines. I imagine all the slides are silky smooth. Great candidate for an electronic lead screw.

Thnks for commenting. Yes, you are right.. a good candidate to "upgrade" with an ELS system, either just the longitudenal axis or also the cross-feed. Doing both allowing a complete cycle-control, as shown before using the Rocketronics ELS system. I have been through several of these installations, both 1- and 2-axis, and different motorizing versions, espcially on Myfords and I consider this a very good "value for the investment in time and money"! The slides are newly scraped and with a new ground bed (as this is) it performs very nice..

@@jansverrehaugjord9934 have you seen the clough42 ELS. Less capable but simpler and cheaper. I would love the rocketronics unit but I work in imperial a lot and he doesn’t seem to want to add a bit of code to allow that. I think imperial offends his sensibilities 😜.

[@jansverrehaugjord9934]

@@sblack48 Yes, I have seen the Clough42 featured. Is this also now 2ch? PS! They may be working on Imperial units for the Rocketronics system.. contact them and ask to be certain.

@@jansverrehaugjord9934 no it’s simple longitudinal feed only, but quite inexpensive.

It's more than Super now! I suspect a lot of model steam engine building in its future.

[@jansverrehaugjord9934]

Thnks! Yes, could be it will make steam engines :)

Hi Did this model have a clutch on as no seen it being used Steve

[@jansverrehaugjord9934]

Yes, this Super 7 MK1 had a clucth originally, but I opted to remove the old style clutch that was mounted as this had some "issues". With a 3 phase motor and a VFD as this machien is set up with you can swicth on/off "indiscrimatively" and I find that I no longer use the clutch
