I think there would be a huge variation. A cheap $100 consumer sewingmachine would not be at strong as an industrial sewing machine that sells for 20 times as much.
One problem with many homemade gentry machines is that people us too-thin material for the base. If the gantry rails are screwed to a sheet of plywood, the entire machine will be as rigid as a sheet of plywood. I’ve been working on some kitchens lately and visiting granite yards. They typically have cut-off leftovers for not a lot of money. A slab of stone would be much better than a plywood sheet and not expensive if it only has to be sewing machine sized. > On May 20, 2023, at 9:28 AM, Thomas J Powderly <tjt...@gmail.com> wrote: > > > I saw an overarm router recently > > and wondered if a sewing machine frame was stiff. > > Compared to a desktop gantry mill. > > > I imagined a makita router mounted on the over arm > > minimal Z travel ( 150mm at most) > > > I can find castings for industrial machines pretty cheap in qty 1 > > What i see are C frames, single casting, with base plate as long as over arm. > > > Any thoughts? > > ( I don't have a sewing machine to lean on ;-) > > > TomP > > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
