Today my kidney stones didn't give me problems, so I was to a local Flea Market and ........
I got a new tool for my shop, the intention is to use it as to build Amp Cabinets and Speaker Box :icon_biggrin:

nice find, be VERY carful when you go to rip a board, cross cut not a problem. I'm sure I'm not the only one that has launched a board !!
-
Very cool! (All I have is an 8" Craftsman table saw.) Enjoy it!
-
The tool arrived yesterday
I'm happy, all seems to be as espected, only a pair of movements were a bit blocked because the dried old lubricant, a small time, a bit of WD40 and all is fixed
Now I must build a solid base (with wheels) and an aspiration

> a solid base (with wheels)
No wheels in the direction of ripping!!
Table saws are obviously dangerous. Radial arm saw looks safer, and can be a fine cross-cut, with less risk of pushing-over like a table-saw, but you really want *different* blades than you use on table-saws (different tooth angle). When I had a $20 radial-arm I discovered it is now hard to get the right blades.
The trick of turning the head to rip boards seems to be especially dangerous, though I never got that far with mine. Using standard blades for cross-cut, I had several frightening "grabs" and quit trying it.

Radial arm saws excel at crosscuts. In fact, they are quite commonly referred to as cutoff saws. And Dewalt has always been the king of radial arms. But they are weak at ripping. You absolutely must use a rip blade and keep the saw in perfect parallel alignment with the fence when ripping. It's very easy for that alignment to get out of cal. And use the anti-kickback system when ripping.
Many years ago I was ripping a bunch of 3/4 x 3/4 stock from 8" wide oak stock. Doing everything by the book. Just as I was finishing a rip (after many successful rips) the blade caught the 3/4 strip and shot it like a spear across my shop. Penetrated the inner wall. I've purposely left that hole as a reminder. So, be careful. Ripping is always trying to lift the workpiece off the table.
Crosscuts can be dangerous too because the blade is always trying to run toward you! You must use a stiff arm with your elbow locked and applying pressure against the blade. It's easy to forget this and get lazy when cutting small stock because it cuts like butter. But if you let this lazy spill over into cutting some 2" hardwood better look out!
Have fun but be safe. I've been using a 10" radial arm for 40+ years. I've had the blade to lock up several times but that one kickback spear is the only close call I've had.

Very nice! Glad you found it. Cabinet construction is something I enjoy and I do have a too many really, but I did just get another pair of Altec 417's that need a home. :icon_biggrin:
Enjoy it!

Altec 417's
give them a good home! AND something in front to push 'em just a bit :icon_biggrin:

Not to hyjack the thread too bad, I am working on a vintage style tube amp, tube preamp, actually I am cloning a Marantz 7 preamp. Just found an older Thorens table and have some Altec Lancing loaded Heatkits AS101 a kind hearted person let me have for a nice deal. Problem is the SPL of the 15's I have are 100 and the horns are 106. 417's being a musical speaker may just need a 50 watt geetar amp.
I have made a few HiFi cabnets now and just learning how to tune them. My main go to is table saw, but I am still not a very good woodworker.
I'll bet K makes some very nice stuff.

I spent enough time in his country to know craftsmanship IS a passion!
cloning a Marantz 7 preamp
I bought a 7 preamp board, well built, sounded great. Once you get the "tuning" down, I might pester ya :icon_biggrin:

Not to hyjack the thread ......

Absolutely NO problem, talk about whatever you want here
Many Thanks PRR & Steve

Cool find!
I recognize every cut. Our school inherited some Army barracks and the internal posts and braces were exactly those big pieces of lumber. (Probably nowhere near where that was shot but they were all from the same set of plans.)
There is a description online of "a mile of DeWalts" used to build Levittown. Returning soldiers had their discharge pay, government loans, wives and children. But the US (the world) built few houses in the 1930s and none in the War. William Levitt (https://en.wikipedia.org/wiki/William_Levitt) got rich(*) building small cheap decent houses on farmed-out potato fields on Long Island NY. Nothing like those big posts, but millions of studs and rafters. I'm also in awe of how they cut rafter notches and stair stringers zip-zip-zip.
(*)Eventually, several "towns" and thousands of houses later, a 237 feet (72 m) yacht.
