hole about 10mm dia along 20mm thk ali plate 200mm through?

I have stolen the casters off of a couple of mine for other projects.

You are right I considered it, but went with other priorities including learning a lot of building skills first to get the ourbuilding in order. Machine tools would have gone through a winter with everything very damp. Did alright with my mineral processing experiments during "the land of perpetual darkness" with a month January into February where someone commented in the pub that they never went out for that month.

No machine tool yet - but thanks for the suggestion...

Best wishes all.

Would be useful for sawing-up weld samples. thanks

Hello again and thanks for responses. I found my original idea non-viable after doing some heat calculations. The change of design meant yes surface water-cooling channels in "clamped-on blocks" with gaskets - suggested here and rightly so - would be the way to go. Changes the ali. I need to order. Thanks for the input and suggestions. Rich S

I use mine for rough and finish carpentry and even cutting firewood, with a

6/10 TPI blade, and EMT electrical conduit with a 24 or 32 TPI blade. It was perfect for cutting smooth and square ends in 6" landscaping timbers for a retaining wall. It cut all the steel for my sawmill, overhead gantry and tractor bucket loader.

Its hardest task was shortening a W10x30 steel beam for a house restoration, that took separate cuts from both sides. It had no trouble with the 4" square x 1/4" supporting columns.

You might find a lot of construction experience in this group, though American house building practice evolved away from British due to our plentiful pine timber and weather extremes. Masonry or steel are standard for commercial buildings but not houses. It's generally concrete block or brick above ground, poured concrete below, cut stone is rare. Interior wall covering is almost always sheetrock, which is plaster sandwiched between cardboard.

haven't seen much of the stucco exterior that became common in postwar Germany, or their Rolladen window shutters. There's much variation here, including log cabins, round yurts and geodesic domes. At a crowded party in a yurt I asked my dog to go sit in a corner, and she walked all around it looking for one.

areas that get snow the lowest beam-supported floor may be slightly raised a foot or three above ground level atop a concrete basement with small windows for lighting along the upper edge. I think that's why ground and first floor are the same here.

My sister's husband restored their ~1790 farmhouse and added a barn using traditional timber framing. I've used it for firewood storage sheds with simpler exposed metal fasteners and less custom joinery with hand tools. I can make panel doors for cabinets from smaller and lighter stock and replaced or rebuilt the deteriorating exterior deck, doors and windows on this house.

This is the borrowed tool that enabled me to cover all the exterior door and window trim with white aluminum flashing after replacing it with pressure treated wood.

Our electrical standards are different. The supply is 240 volt 60 Hz, center-tapped at the utility transformer to give two 120 legs or "phases" for wall outlets and small appliances. Each circuit breaker or fuse supplies a linear string of outlets on typically 12 gauge (3.3 mm^2) pairs with a separate safety ground, no ring mains like you have. Ceiling lights are on different breakers from the wall outlets so one tripped breaker leaves a light source available. Higher powered equipment like stoves and water heaters take 240V. I used the 240V 30A circuit that had powered an electric fireplace heater for my 60 gallon air compressor.

When tracing outlet circuit breakers a vacuum cleaner on the floor makes a low pitched sound that carries better than voice or music.

I helped build an industrial test stand that rapidly temperature cycled automotive ignition modules on copper plate heatsinks with copper tubing hard soldered (95/5) to the back. The copper was bent into U channels for stiffness to keep the contact surface flat.

The circulating fluid was Therminol that tolerates a much wider temperature range than water, which the system would have alternately frozen and turned into high pressure steam.

Strip heaters are available if you want to start at a controlled elevated temperature.

---------------------------- The fluid may have been UCON from Dow. Both were mentioned.

Easy alternatives are car (ethylene glycol) and RV (propylene glycol) which have higher boiling points. Both are flammable and car antifreeze is toxic. Junkyard car parts could circulate and cool them.

Another to look into is silicone brake fluid though it's not ideal either.
